Since the solution 2,-1 does check. Pay close attention to the key words given below, as this will help you to write the inequality.

If you represent it with a variable, can you write an equation that models the relationship among the quantities described in the problem.

Before all that, let us define the different inequality signs: To get a different worksheet using the same options: Correctly uses a computational strategy but writes an incorrect equation. Determine the equations and solve the word problem. The number of weeks that Keith can withdraw money from his account is 12 weeks or less.

We thus refer to the third point as a "checkpoint. The point 0,b is referred to as the y-intercept. Be sure the student understands the conventions in graphing inequalities and their meaning e.

Example 2 Sketch the graph and state the slope of Solution Choosing values of x that are divisible by 3, we obtain the table Why use values that are divisible by 3. What are some possible amounts of time that the athlete can run and jog in order to meet her goal of burning at least calories.

Of course, we could also start by choosing values for y and then find the corresponding values for x. The actual point of intersection could be very difficult to determine.

Partially solves the inequality using a numerical approach before writing it. Usually, equations are written so the first term is positive. Solution Placing the equation in slope-intercept form, we obtain Sketch the graph of the line on the grid below.

Before going to learn how to write inequalities, we must know about two shapes. Examples of Student Work at this Level The student writes the correct equation but then: Solution Step 1 Both equations will have to be changed to eliminate one of the unknowns.

If both Alex and Billy get three more coins each, Alex will still have more coins than Billy. Compare the coefficients of x in these two equations. We indicate this solution set with a screen to the left of the dashed line. In the same manner the solution to a system of linear inequalities is the intersection of the half-planes and perhaps lines that are solutions to each individual linear inequality.

At least is a key word that notes that this problem must be written as an inequality. Then the graph is The slope of We now wish to compare the graphs of two equations to establish another concept. Students should identify the variables and also identify the constraint time, etc.

Note that in this system no variable has a coefficient of one. Is a solution. What would the solution of your equation indicate about the answer to the question posed in this problem.

Therefore, 3,4 is a solution to the system. Instructional Implications Work with the student on modeling relationships among quantities with equations. This is because addition and subtraction have no effect on the inequality sign. Determine the common solution of the two graphs.

We must now check the point 3,4 in both equations to see that it is a solution to the system. What if our athlete wants to meet her goal exactly. Instructional Procedures View To begin the lesson, provide the following situation to students: How do you choose which one to use. We now locate the ordered pairs -3,9-2,7-1,50,31,12,-13,-3 on the coordinate plane and connect them with a line.

Systems of linear inequalities A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.

Solving Word Problems in Algebra Inequality Word Problems. Pay close attention to the key words given below, as this will help you to write the inequality. Once the inequality is written, you can solve the inequality using the skills you learned in our past lessons.

Think about others ways you might use inequalities in real world. absolute value equations and inequalities, which will give them greater insight into the solution process.

Method 1: Graphing. 2. Ask students to graph. y x. 2 3. and. y. 5. the given graph. Then, solve, write the solution set in set-builder notation, and graph the solution set on a number line. Inequalities Word Problem Worksheet write an inequality to represent the scenerio, and solve.

Write a complete sentence to describe your solution. 1) Keith has $ in a savings account at the beginning of the summer. He wants to have at least $ at the Solve each inequality and graph its solution.
